A different perspective:
I have two children, a daughter who is 21, beautiful and will finish her undergrad in Nursing this May. She plans on getting her Masters while she is working, which will start right after graduation. She already has a job lined up. My son is 18 and a sophomore working towards a BSME. He is much smarter than I am and a gifted athlete. He plays college soccer and will be playing PDL this summer.
Yes, children are expensive if raised correctly. We will spend around 200K getting them both through 4 years of college. After that it's their dime lol. It's not the cost though that most important. It's the time. IMO, to be a good parent, you must commit every, single, spare, moment of every single day to being a parent. You must forgo all the things you think are fun right now and divert your full attention to raising that lifeform you created. It's not a job for everyone, although there are a lot of people having kids that should not. You need to be able to go without sleep, do disgusting tasks dealing with diapers, become a human troubleshooter for illness (hmmm, they just ate and they still are crying...why?) and basically just change your life. Sounds terrible.
Well, from that first moment in the hospital, you just started the longest project you will ever do, the hardest challenge you will ever complete and you will be tested like you never have before.
You want to climb Mt. Everest? Free dive 600 ft in the Indian Ocean? Sky dive? Hang Glide? Those are easy compared to raising a child correctly. Cheap too.
I have been working on my "projects" for 21 years and one of them is just about complete. When she goes completely on her own she will be a wonderful nurse, a good wife and above all a good person. I still have a few years to complete the other project but he is well on his way to being a good engineer who will probably design some amazing new device or we will watch him on ESPN playing soccer. We will see.
I guess what I am trying to say is not everyone is cut out to be a parent. Some would make great parents but choose not to and some, well let's just say they made the right decision.
I have travelled the world with my job. I have been in some of the worst places on six continents. I have designed some pretty amazing stuff over the years. I have raced motorcycles, raced bicycles, modded many vehicles, snow skied, water skied, bungee jumped and climbed mountains. Nothing I have ever done has been as hard, complicated, frustrating or expensive as raising two children with my wife. Nothing has ever been as fun, happy, satisfying, rewarding and amazing either.
I gave my daughter her first bottle 21 years ago. This summer I bought her a Margarita at the beach on her 21st birthday. Think about it.
